deformable solids with applications on human face and body

just found this

Research

My research is aimed at developing algorithms for the simulation of deformable solids with applications on human face and body animation, facial expression analysis and virtual surgery. Individual projects include:

� Visual speech synthesis using muscle-driven face models
Image
� Robust quasistatic simulation algorithms for flesh simulation (with Joey Teran, Geoffrey Irving and Ron Fedkiw)
Image
Image
� Estimation of muscle activations in the human face from motion captured performances (with Igor Neverov and Ron Fedkiw)
Image
Image
� Simulation of anatomically accurate models of skeletal muscles (with Joey Teran, Cynthia Lau and Ron Fedkiw)

Thanks.
We know it...but we use a different tecnology..more "artist oriented".
We have tried to add skeletons, muscles, etc..but the mesh is too heavy to compute, to morph, to optimize, etc...
so we have choosed a different algo (not released yet, very different from MH 0.9.1).

Cheers,

Manuel

btw. http://www.math.ucla.edu/~sifakis/
seems he has changed position and he still publicizes papers

Another of Weta's innovations on "Avatar" was a new system for developing the way that muscles are produced for computer-generated characters. Letteri said that in the past, most visual effects studios would have crafted characters' skeletons and simply layered the digital muscles on top. But, he said, that's not how real muscles work. Instead, they have fibers that are firing up and down the body, and so for "Avatar," Weta "re-wrote our muscles to be correct biomechanically."

so high end goes straight to more realistic physics...
